In an excerpt from the revealing book, Luongo recalls Stallone splashing out on dinner with U.S. tycoon Ronald Perelman at exclusive Upper East Side eatery Coco Pazzo, only to have his assistant call to complain about his extortionate tab.

Luongo writes, "Stallone was shocked to see that he had an $800 (Â£432) wine tab. If he can't afford or doesn't want to spend a lot of money on wine, then he shouldn't order things without asking how much they cost."
